Description

Technical Field

[0001] This utility model relates to the field of particulate matter filling technology, and in particular to a vibrating particulate matter feeding device. Background Technology

[0002] Granule feeders are core auxiliary machines in production lines for powdered food, pharmaceuticals, and chemicals. Their metering accuracy and continuous feeding capacity directly determine packaging speed and yield. Existing equipment generally adopts a vertical gravity structure, relying on the weight of the granules to fall into the metering cup and then be discharged. This approach is prone to "bridging" and "wall adhesion" phenomena in the case of viscous, irregular, or oily granules, leading to pipeline blockage, metering inaccuracies, frequent shutdowns for cleaning, and significant manual intervention.

[0003] To address the clogging problem, the industry has developed transverse transmission indexing devices (such as CN221189192U). These devices change the material feeding direction from vertical to horizontal, using a pusher plate to transversely transport particles, causing them to move intermittently between the storage hole and the feeding hole, significantly reducing the probability of jamming. Simultaneously, double-layer limiting by a fixed plate and a bottom plate achieves quantitative cutting, with measurement stability superior to traditional gravity-type devices. However, its structure still includes a bottom plate, fixed plate, pusher plate, chute, blowing device, and multiple sets of agitators, resulting in numerous parts, complex assembly, and high manufacturing and maintenance costs, limiting its adoption in small and medium-sized production lines. Therefore, the market urgently needs a feeder that retains the anti-clogging advantages of transverse transmission while further simplifying the structure and reducing costs. Summary of the Invention

[0004] In view of the above-mentioned technical problems existing in the prior art, the purpose of this application is to provide a vibrating particulate feeding device with simple structure and low production cost.

[0005] The technical solution adopted in this application is as follows:

[0006] A vibrating particulate feeding device includes a storage hopper, a feeding assembly installed at the bottom of the storage hopper, an XY axis linear motion mechanism, and a baffle plate;

[0007] The storage hopper is used to store particulate matter to be fed;

[0008] The feeding assembly is installed at the bottom of the storage hopper, and the feed inlet of the feeding assembly is connected to the discharge outlet at the bottom of the storage hopper. The feeding assembly is used to feed the granular material in the storage hopper outward.

[0009] The baffle plate is used to fit the discharge port of the feeding assembly to prevent particles from falling out uncontrollably;

[0010] The storage hopper is fixedly mounted on the XY-axis linear motion mechanism via a feeding assembly. The XY-axis linear motion mechanism is used to precisely control the feeding assembly and the entire storage hopper to move in the X and Y axes, thereby achieving movement on the horizontal plane and causing the discharge port of the feeding assembly to be in contact with or away from the baffle plate.

[0011] Furthermore, the storage hopper is a closed container for storing particulate matter. The top of the storage hopper is equipped with a level gauge port and a feeding pipe port. A level gauge is inserted into the level gauge port to detect the volume of particulate matter in the storage hopper, thereby controlling the feeding of particulate matter through the feeding pipe port. The bottom of the storage hopper is equipped with a discharge port to discharge particulate matter, which enters the feeding assembly.

[0012] Furthermore, the feeding assembly includes a motor vibration assembly, a fixed plate, and a discharge trough cavity. The motor vibration assembly is mounted on the XY-axis linear motion mechanism, and the fixed plate is mounted on the motor vibration assembly. The upper surface of the fixed plate is welded to the lower surface of the discharge trough cavity. The upper end of the discharge trough cavity is threadedly connected to and communicates with the lower end of the storage hopper. A discharge pipe is connected to one side of the discharge trough cavity. The discharge pipe communicates with the material inside the storage hopper through the discharge trough cavity, and the outlet of the discharge pipe is the discharge port of the feeding assembly.

[0013] Furthermore, the motor vibration assembly includes a base plate, a motor, and a motor housing. The motor housing has a square or rectangular cavity structure, and its lower surface is fixedly mounted on the base plate. The base plate is fixedly mounted on the XY-axis linear motion mechanism. A fixing plate is fixedly mounted on the upper surface of the motor housing.

[0014] The motor is installed inside the motor housing and can provide the motor housing with a horizontal reciprocating vibration. The motor housing then transmits the force to the storage hopper through the fixing plate and the discharge trough cavity, so that the material in the bottom of the storage hopper is continuously discharged from the discharge port under the action of inertia.

[0015] Furthermore, the motor housing is filled with shock-absorbing cotton to reduce the impact force of the motor on the housing; the lower surface of the motor housing is connected to the base plate with foam adhesive.

[0016] Furthermore, the discharge trough cavity has a hollow cuboid structure, and a storage chamber is provided inside. The lower end of the storage hopper is fixedly connected to the storage chamber and the two are in communication. A connecting pipe cavity is provided on one side of the discharge trough cavity. The connecting pipe cavity is machined with internal threads and fitted with a connecting nut. The nut has a central hole and is welded and fixed to the discharge pipe.

[0017] Furthermore, it also includes a base, on which the XY axis linear motion mechanism and the lower end of the baffle plate are respectively fixedly mounted. The upper end of the baffle plate is located in front of the discharge port of the feeding assembly and can be tightly fitted with the discharge port.

[0018] Furthermore, the baffle plate is a metal sheet.

[0019] Furthermore, the XY-axis linear motion mechanism includes an X-axis lead screw sliding assembly and a Y-axis lead screw sliding assembly disposed on the X-axis lead screw sliding assembly; both the X-axis lead screw sliding assembly and the Y-axis lead screw sliding assembly include a support plate, a lead screw disposed on the support plate, a ball nut disposed on the lead screw, a movable plate disposed on the ball nut, and a drive motor fixed on the support plate for driving the lead screw to rotate.

[0020] Compared with the prior art, the beneficial effects achieved by this application are:

[0021] 1. The modular feeding process replaces the manual loading process, which can realize the synchronous loading of one or more components of materials, and significantly improves the efficiency of operation.

[0022] 2. CNC linkage ensures that the interfaces of each component are flat and the thickness is uniform, eliminating the ratio fluctuations caused by traditional mixing and enhancing experimental reproducibility;

[0023] 3. Modular units can be quickly added or removed in quantity and adapted to various containers such as tubes, bags, and bottles without the need to modify the production line, reducing equipment investment and maintenance costs, resulting in low production costs and applicability to various production processes.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figure 1 and Figure 2 As shown, a vibrating particulate feeding device includes an XY axis linear motion mechanism, a baffle plate, a storage hopper 1, and a feeding assembly installed at the bottom of the storage hopper 1. The baffle plate is a metal plate, and the storage hopper 1 is a closed container for storing particulate matter. A discharge port is provided at the bottom of the storage hopper 1 to discharge particulate matter, and the discharged particulate matter enters the feeding assembly.

[0032] The feeding assembly includes a base plate 2, a motor 3, a motor housing 4, a fixing plate 5, a discharge trough cavity 6, and a discharge pipe 7. The motor housing 4 is a square or rectangular cavity structure, and its lower surface is fixedly mounted on the base plate 2. The fixing plate 5 is detachably fixed to the upper surface of the motor housing 4 by bolts 8. The upper surface of the fixing plate 5 is welded to the lower surface of the discharge trough cavity 6. The upper end of the discharge trough cavity 6 is threadedly connected to and communicates with the lower end of the storage hopper 1. The discharge trough cavity 6 is a hollow rectangular structure with a storage chamber inside. The lower end of the storage hopper 1 is fixedly connected to and communicates with the storage chamber. Figures 1-2 In the middle, a connecting pipe cavity 10 is provided on one side of the discharge trough cavity 6. The connecting pipe cavity 10 is machined with internal threads and fits with a connecting nut. The nut has a central hole and is welded and fixed to the discharge pipe 7.

[0033] The motor 3 is installed inside the motor housing 4 and can provide the motor housing 4 with a reciprocating vibration in the horizontal direction. The motor housing 4 then transmits the force to the storage hopper 1 through the fixing plate 5 and the discharge trough cavity 6, so that the material in the bottom of the storage hopper 1 is continuously discharged from the discharge port under the action of inertia.

[0034] During motor operation, the storage hopper 1 and the feeding assembly vibrate as a whole, allowing material to fall from the storage hopper into the discharge trough cavity 6 and be discharged through the discharge pipe 7. This overall vibration process prevents material blockage in the storage hopper 1, discharge trough cavity 6, and discharge pipe 7. Furthermore, the motor housing is filled with shock-absorbing cotton 12 to prevent excessive collisions between the cotton and the motor housing during operation, which could affect the motor's lifespan. The shock-absorbing cotton is located on the left and right sides inside the motor housing, not in the forward and backward reciprocating motion direction provided by the motor 3.

[0035] The lower surface of the motor housing 4 is connected to the base plate 2 by foam adhesive. The foam adhesive serves to bond the base plate and the motor housing 4, and at the same time, it can act as a shock absorber to reduce the mechanical impact force on the base plate when the motor is running.

[0036] In another embodiment of this application, a level gauge port 9 and a feeding pipe port 11 can be provided at the top of the storage hopper 1. A level gauge and a feeding pipe can be installed respectively, so that after the material flows out from the discharge pipe 7, the material level in the storage hopper 1 drops to a certain range, and then the material can be replenished from the storage tank through the feeding pipe. Furthermore, when the material in the storage hopper reaches a certain height, the feeding pipe will automatically close, stopping the feeding.

[0037] The device of this application also includes a base, and the lower end of the XY axis linear motion mechanism and the baffle plate are respectively fixedly mounted on the base. The upper end of the baffle plate is located in front of the discharge port of the feeding assembly and can be closely fitted with the discharge port.

[0038] The XY-axis linear motion mechanism includes an X-axis lead screw sliding assembly and a Y-axis lead screw sliding assembly mounted on the X-axis lead screw sliding assembly. Both the X-axis and Y-axis lead screw sliding assemblies include a support plate, a lead screw mounted on the support plate, a ball bearing nut mounted on the lead screw, a movable plate mounted on the ball bearing nut, and a drive motor fixed to the support plate for driving the lead screw to rotate.

[0039] The support plate of the X-axis lead screw sliding assembly is fixedly mounted on the base, and the support plate of the Y-axis lead screw sliding assembly is fixedly mounted on the moving plate of the X-axis lead screw sliding assembly. The base plate 2 of the unloading assembly is then fixedly mounted on the moving plate of the Y-axis lead screw sliding assembly. Thus, under the action of the drive motor of the X-axis lead screw sliding assembly, the entire Y-axis lead screw sliding assembly and the unloading assembly can move linearly along the X-axis; under the action of the drive motor of the Y-axis lead screw sliding assembly, the unloading assembly can move linearly along the Y-axis.

[0040] The baffle plate is a thin metal sheet, located at the front end of the discharge pipe and tightly fitted to the pipe opening. During operation, the XY-axis linear motion mechanism displaces the entire feeding assembly, moving the discharge pipe outlet away from the baffle plate; subsequently, the motor starts, performing reciprocating vibration feeding. After feeding is completed, the XY-axis linear motion mechanism resets the feeding assembly, causing the discharge pipe opening to re-fit against the baffle plate, thereby preventing residual powder samples from the storage hopper, discharge trough, or discharge pipe from accidentally falling out.

[0041] The above provides a detailed description of the vibrating particle feeding device provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
